Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.Under
Face is described in detail the embodiment of the present invention in conjunction with attached drawing, please refers to Fig.1 to Fig.3.
A kind of endergonic structure that anti-pendant is hit, comprising: frame 1, floor crossmember 2 and jointing 3；
First installation side 32 of the bottom surface by the first web 31 and on the first web 31 of jointing 3 forms；
First web 31 is provided with the first U-type groove 33 close to one end of floor crossmember 2, and the first U-type groove 33 is towards floor
Notch is arranged in 2 side of crossbeam；
Floor crossmember 2 is formed by the second web 21 and positioned at the second installation side 22 of 21 upper bottom surface of the second web；Second abdomen
The second installation of 21 upper bottom surface of plate setting side 22, selects unilateral setting installation side, facilitates about 31 the first web of jointing of insertion
In first installation side 32 of bottom surface；
Second web 21 is provided with the second U-type groove 23 close to one end of jointing 3, and the second U-type groove 23 is towards connection
Notch is arranged in 3 side of connector；
Floor crossmember 2 is inserted into jointing 3 by the second installation side 22, and the second web 21 and the first web 31 are closely
2 side of plate crossbeam posts and fixes, and the other side of the first web 31 and frame 1 are fixed, makes the first U-type groove 33 and the second U-type groove
23 notch overlaps, and weakens the coupling stiffness between floor crossmember 2 and frame 1, can produce bigger deformation, thus
The energy that absorbing frame 1 transmits reduces the pendant being transmitted to occupant and hits power.
In the present embodiment, the first web 31 of jointing 3 and installation side 32 are integrally machined molding, ensure that jointing
Load-bearing intensity.
In the present embodiment, the first web 31 has been uniformly arranged rivet hole, the first web 31 by rivet respectively with the second abdomen
